Uptake of Front-of-Package Nutrition Labeling Scheme after 5 Years of Adoption in Thailand: An Analysis of New Launched Pre-Packaged Food and Beverages Products.

In 2016, Thailand introduced voluntary front-of-pack nutrition labeling, the 'Thailand Healthier Choice' logo (THCL), in order to help consumers make informed, healthier food choices in each food category. This study aimed to assess the uptake of the THCL scheme in Thailand after five years of implementation by analyzing a newly launched product database. Data on the nutritional composition and labeling were obtained from the Mintel Global New Products Database between 2017 and 2021. The product's healthfulness was determined using the Health Star Rating (HSR) algorithm. The numbers and proportions of total, eligible, and labeled products bearing the THCL logo were analyzed and classified by food category, by HSR value, and by manufacturer. After 5 years of implementation, THCL uptake as a proportion of total products and eligible products continues to increase by 3.0% and 10.2% per annum, respectively. The logo has correspondingly appeared on 10.7% and 39.5% of total and eligible products. As a voluntary implementation, 76.1% of products displaying the THCL logo belonged to the 'non-core' group, i.e., non-alcoholic beverages and instant foods. This food category (HSR < 3.0) was more likely to register to bear THCL rather than those 'core' food scoring an HSR ≥ 3.5, which might reflect economic considerations and benefits. The present analysis also found that only 10% of manufacturers in Thailand launched 'healthier' products that display the THCL logo with varied product numbers. To summarize, the initial five-year implementation of the THCL program shows promise, but its adoption remains limited and inconsistent, thereby restricting its influence on public health. Our discoveries highlight the limitations of commercial goodwill in applying THCL voluntarily in Thailand and offer potential suggestions to enhance its adoption in the coming years.
